Effects of Immediate Postpartum Diuretic Treatment on Postpartum Blood Pressure among Individuals with Hypertensive Disorders of Pregnancy: A Systematic Review and Meta-Analysis.

Background: Hypertensive disorders of pregnancy (HDP) are associated with ongoing postpartum hypertension (HTN) and increased morbidity. Extravascular water and sodium mobilization is implicated in postpartum blood pressure (BP) elevation, however trials of postpartum diuretics in HDP have had mixed results. Our meta-analysis aimed to analyze the impact of postpartum diuretics on postpartum hypertension following HDP.

Patterns of physical activity, sedentary behavior, and sleep across pregnancy before and during two COVID pandemic years.

Background: Physical activity is recommended during pregnancy, and high sedentary behavior and poor sleep may increase the risk of pregnancy complications. Activity patterns and sleep were negatively impacted by the COVID pandemic in many segments of the population, but the impact of the pandemic on pregnant people is understudied. We aimed to compare patterns of physical activity, sedentary time, and sleep during pregnancy between a pre-COVID and a COVID-era cohort.

Association of Race and Ethnicity and Social Factors With Postpartum Primary Care or Cardiology Follow-Up Visits Among Individuals With Preeclampsia.

Background: Preeclampsia is associated with increased cardiovascular morbidity and death. Primary care or cardiology follow-up, in complement to routine postpartum obstetric care, provides an essential opportunity to address cardiovascular risk. Prior studies investigating racial differences in the recommended postpartum follow-up have incompletely assessed the influence of social factors.

Remote blood pressure management for postpartum hypertension: a cost-effectiveness analysis.

Background: Recognizing the importance of close follow-up after hypertensive disorders of pregnancy, many centers have initiated programs to support postpartum remote blood pressure management.

Objective: This study aimed to evaluate the cost-effectiveness of remote blood pressure management to determine the scalability of these programmatic interventions.

Study Design: This was a cost-effectiveness analysis of using remote blood pressure management vs usual care to manage postpartum hypertension.

Perinatal Remote Blood Pressure Monitoring.

Perinatal mortality and severe maternal morbidity among individuals with hypertensive disorders of pregnancy (HDP) are often driven by persistent, uncontrolled hypertension. Whereas traditional perinatal blood pressure (BP) ascertainment occurs through in-person clinic appointments, self-measured blood pressure (SMBP) programs allow individuals to measure their BP remotely and receive remote management by a medical team. Though data remain limited on clinically important outcomes such as maternal morbidity, these programs have shown promise in improving BP ascertainment rates in the immediate postpartum period and enhancing racial and ethnic equity in BP ascertainment after hospital discharge.

A smartphone application toward detection of systolic hypertension in underserved populations.

High systolic blood pressure (BP) is the most important modifiable risk factor for cardiovascular disease. Managing systolic hypertension is especially difficult in underserved populations wherein access to cuff BP devices is limited. We showed that ubiquitous smartphones without force sensing can be converted into absolute pulse pressure (PP) monitors.

Clinical Outcomes Associated With a Remote Postpartum Hypertension Monitoring Program.

Objective: To evaluate differences in health care utilization and guideline adherence for postpartum individuals with hypertensive disorders of pregnancy (HDP) who are engaged in a remote monitoring program, compared with usual care.

Methods: This was a retrospective cohort study of postpartum individuals with HDP who delivered between March 2019 and June 2023 at a single institution. The primary exposure was enrollment in a remote hypertension management program that relies on patient home blood pressure (BP) measurement and centralized nursing team management.

Postpartum Weight Change Association With Readmission and Blood Pressure Trend Among Individuals With Hypertensive Disorders of Pregnancy.

Background: The aim of this study was to evaluate the association between early postpartum weight change and (1) hospital readmission and (2) 2-week blood pressure trajectory.

Methods And Results: This retrospective study cohort included 1365 individuals with a hypertensive disorder of pregnancy enrolled in a postpartum hypertension remote monitoring program. Exposure was percentage weight change from delivery to first weight recorded within 10 days postpartum.

Postpartum Ambulatory Blood Pressure Patterns Following New-Onset Hypertensive Disorders of Pregnancy.

Importance: After a hypertensive disorder of pregnancy, hypertension can worsen in the postpartum period following hospital discharge. Risk factors for ongoing hypertension and associated outcomes have not been well characterized.

Objective: To identify risk factors and characterize outcomes for individuals with ongoing hypertension and severe hypertension following hospital discharge post partum through a hospital system's remote blood pressure (BP) management program.

Quantum critical fluctuations in a transverse-field Ising magnet.

CoNbOis a model system for a spin-1/2 one-dimensional (1D) transverse-field Ising magnet (TFIM) with a rather low three-dimensional (3D) Néel ordering temperature atTN=2.95K. We studied CoNbOusing ultrasound measurements down to 0.

Lung Protective Ventilation during Pregnancy: An Observational Cohort Study.

 We sought to describe characteristics of mechanically ventilated pregnant patients, evaluate utilization of low-tidal-volume ventilation (LTVV) and high-tidal-volume ventilation (HTVV) by trimester, and describe maternal and fetal outcomes by ventilation strategy.  This is a retrospective cohort study of pregnant women with mechanical ventilation for greater than 24 hours between July 2012 and August 2020 at a tertiary care academic medical center. We defined LTVV as average daily tidal volume 8 mL/kg of less of predicted body weight, and HTVV as greater than 8 mL/kg.

The sedentary behavior reduction in pregnancy intervention (SPRING) pilot and feasibility randomized trial.

Pregnant individuals rarely achieve moderate-to-vigorous intensity physical activity recommendations.Purpose The sedentary behavior reduction in pregnancy intervention (SPRING) pilot and feasibility randomized trial aimed to demonstrate feasibility, acceptability, and initial efficacy of a lower intensity intervention targeting reduced sedentary behavior and increased standing and steps.Methods First trimester pregnant individuals at risk for high sedentary behavior and adverse pregnancy outcomes (APO) were randomized 2:1 to a multi-component sedentary behavior reduction intervention or no-contact control.

Pressure-tuned quantum criticality in the large-D antiferromagnet DTN.

Strongly correlated spin systems can be driven to quantum critical points via various routes. In particular, gapped quantum antiferromagnets can undergo phase transitions into a magnetically ordered state with applied pressure or magnetic field, acting as tuning parameters. These transitions are characterized by z = 1 or z = 2 dynamical critical exponents, determined by the linear and quadratic low-energy dispersion of spin excitations, respectively.

Blood Pressure Trajectories Through the First Year Postpartum in Overweight or Obese Individuals Following a Hypertensive Disorder of Pregnancy.

Background: Hypertensive disorders of pregnancy are associated with cardiovascular disease; however, patterns of blood pressure (BP) recovery are understudied. We compared pregnancy and postpartum BP trajectories among individuals with hypertensive disorders of pregnancy who developed persistent hypertension at 1-year postpartum compared with individuals with normalization of BP.

Methods: We used data from a randomized clinical trial of individuals with overweight, obesity, and hypertensive disorders of pregnancy conducted in the first year after delivery.

The effect of a neonatal sleep intervention on maternal postpartum hypertension: a randomized trial.

Background: In nonpregnant adults, poor sleep is associated with higher blood pressure. Poor sleep is common in the postpartum period and is often attributed to infant caretaking needs. However, its effects on cardiovascular health in individuals with a hypertensive disorder of pregnancy are unknown.

Neighborhood Deprivation, Perceived Stress, and Pregnancy-Related Hypertension Phenotypes a Decade Following Pregnancy.

Background: Hypertensive disorders in pregnancy and other adverse pregnancy outcomes (APOs) increase the risk of developing chronic hypertension and cardiovascular disease. Perceptions of stress and neighborhood context also influence blood pressure (BP) fluctuations. We examined if APOs, higher perceived stress, and neighborhood deprivation were associated with hypertension phenotypes a decade after pregnancy in untreated individuals.
